Abstract
Tooling (10) for making slots in a multistage disk (1) by electrochemical machining. The tooling comprises first and second rings (20) arranged coaxially about a disk axis and configured to act as cathodes, each ring having an inside periphery with a plurality of radial machining projections. The first and second rings (20) are rigidly secured relative to each other. A method of making slots in a multistage disk by electrochemical machining using such a tool.
Claims10
Tooling for making slots in a multistage disk by electrochemical machining, wherein the tooling comprises at least a first ring and a second ring, each arranged coaxially about an axis of the disk, and configured to act as a cathode for machining a respective one of two stages of different diameters of the disk, each ring having an inside periphery with a plurality of radial machining projections, the first and second rings being rigidly secured to each other.
